Drill Bit GEKO SDS Plus 16 mm x 210 mm - model G61621

The GEKO SDS Plus drill bit 16 mm x 210 mm (model G61621) is a rotary-hammer bit designed for creating 16 mm diameter holes in masonry, concrete and natural stone. It has an overall length of 210 mm and a shank compatible with SDS Plus chucks, enabling straightforward fitting and stable operation in SDS Plus rotary hammer drills. The design focuses on efficient material removal and reliable centring when drilling fixed-position holes for anchors, dowels or through-holes in construction and installation work.

Advantages

This drill bit offers compatibility with SDS Plus systems for quick bit changes and secure retention during hammer drilling. Its 16 mm cutting diameter and 210 mm overall length provide a suitable working reach for many common anchoring and fixing tasks. The bit geometry is intended to deliver effective dust evacuation and consistent drilling progress in masonry and concrete substrates. The product is manufactured to serve repetitive use in trade and DIY contexts where a standard 16 mm hole is required.

Suitable for

• Drilling anchor and dowel holes in concrete and masonry
• Making holes for through bolts and fixings in stone and brick
• Preparing holes for installation of pipes and conduits in solid substrates
• General construction and renovation tasks requiring a 16 mm hole

Key specifications

• Shank type: SDS Plus compatible
• Drill diameter: 16 mm
• Overall length: 210 mm
• Suitable materials: masonry, concrete, natural stone
• Intended use: rotary hammer drilling with hammer action

How to use

Fit the SDS Plus shank into the drill chuck until it locks securely. Select a rotary hammer drill with a mode for hammer drilling and set the recommended rotation speed and hammer action as specified by the drill manufacturer for 16 mm masonry drilling. Mark the drilling point, start at low speed to establish a pilot seat, then apply steady pressure and allow the hammer action to advance the bit. Withdraw the bit periodically to clear dust and debris and maintain cooling and chip removal, particularly when drilling deeper holes.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses, hearing protection and dust mask when drilling. For best results in reinforced concrete, verify whether rebar contact is likely and proceed with suitable rebar-cutting measures or select an alternative method. Ensure the rotary hammer is set to the correct SDS Plus hammer-drill mode and avoid excessive lateral force to preserve bit life and maintain hole accuracy.
